Description

Technical Field

[0001] The present invention relates to the technical field of delayed firing device structure, in particular to an internal energy storage type quasi-fluid delayed firing device. Background Art

[0002] As a throwing type individual weapon and ammunition, the safety of hand grenades is of great importance. Based on the many years of practice of MIL-STD-1316 "Fuze Safety Design Criteria", the US military has issued a special safety design standard for hand-laid weapons, mainly hand grenade fuzes, namely MIL-STD-1911 "Safety Design Criteria for Hand-laid Weapons". my country has adopted it and formulated GJB 3194-1998 "Safety Design Criteria for Hand-laid Weapons". Its requirements include explosion-proof, redundant insurance, delayed release of explosion-proof, permitted explosive charge, safety system failure rate, fault insurance, human factors engineering (simple structure, firm structure, assembly and setting, manual insurance parts, working status indication), internal energy storage, material compatibility, electric ignition energy dissipation, adaptability to electrical and electromagnetic environments, explosive handling and fire prevention, etc.

[0003] According to the US military standard manual MIL-HDBK-145C "ACTIVE FUZE CATALOG", none of the 17 grenade fuze models listed meet the requirements of MIL-STD-1911 "Safety Design Guidelines for Manually Deployed Weapons", including the most basic explosion-proof safety requirements and redundant insurance requirements. In recent years, domestic products have been developed in accordance with the requirements of GJB3194-1998 "Safety Design Guidelines for Manually Deployed Weapons", but some still do not meet the explosion-proof safety requirements, some fail to meet the redundant insurance requirements, or the structure is too complicated, inconvenient to operate and use, and the cost is high.

[0004] After the current hand grenades are thrown and used, the pyrotechnic components of the fuse produce sound, light, and smoke, which is not conducive to the concealment of the user, resulting in easy exposure of the user and reducing the safety of survival on the battlefield. In addition, the current hand grenades have pyrotechnic components in their design, which will produce flames after being used, limiting the use of explosion-proof and anti-terrorism scenarios. Therefore, it is very necessary to invent a firing device that can be used in the three-no (silent, lightless, and smokeless) scenarios of hand-thrown weapons and has a precise delay function. Summary of the invention

[0005] In view of the above problems, the present invention provides an internal energy storage type quasi-fluid delayed firing device, which ensures the concealed operation of the user and has a precise delay function.
